Specification of Letters Patent. Application filed May 28,4907. Serial No. 376,046.

Patented April 28, 1908.

To all whom it may concern:

Be it known that I, WILLIAM,F. KLEWIT TER, a citizen of the United States, and a resident of Mosinee, in the county of Marathon and State of Wisconsin, have invented a new and Improved Loading Device, of which the following is a full, clear, and exact description.

My invention relates to a loading device and has for its principal object to provide a loading device in whlch the strain is evenly distributed through the frame.-

Still another object of the invention is to provide adjustable side braces which may be isposed from the top of the frame to the ound.

Further objects of the invention are to provide a strong and durable loading device, which can be economically constructed and which can be moved and operated under varying and difficult conditions.

In this specification I will describe one I form of my invention, but I do not limit myself thereto as I consider myself entitled to all forms and embodiments which may fall within the scope of the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the inven-' tion; Fig. 2 shows on an enlarged scale the construction of the chains which are to be secured to the load; Fig. 3 is a plan view of the invention shown in Fig. 1 Fig. 4 is an enlarged view showing the pulley secured to the frame of the loading device, through which the hoist rope passes; Fig. 5 shows the method by which the adjustable braces are secured to the frame; Fig. 6 shows the method by which the forward braces of the frame of the loading device is secured to the transverse member of the frame; Fig. 7 shows the method by which the boom is secured pivotally to the frame; and Fig. 8 shows the fastening by which the rear brace is secured to the forward brace.

The longitudinal members 1, of the derrick body are supported in any suitable manner on the wagon frame 2. These longitudinal members 1, are on opposite sides of the wagon frame and are connected by transversemembers 3, which serve as supports for the forward and rear braces 4 and 5, respectively and also for the boom 6. The forward braces sides of the frame.

4 are secured to the forward transverse member 3- of the derrick body by fasteners 7,

which permit the braces to move upward or downward, so that the frame may be lowered or folded on the body of the machine. The

.rear braces 5, are inserted at one end into sleeves 8, on the forward braces 4 and at the other end into holes'in the rear transverse member 3 of the derrick body. By this arrangement, the rear braces 5 may be removed from the rear transverse member 3 and the forward braces 4, which will permit the forward braces to hold on the frame. The said braces 4 and 5 form with the transverse members, obtuse angles looking from the This construction is adopted in order to secure additional strength.

The boom 6' is pivoted as shown in Fig. 7, to the middle transverse member 3, which Will permit the boom to assume any angularity with the body of the frame. The forward braces 4, are connected at their'upper ends by a crossbar 9, which has a groove 10, therein. A guy rope 11 is secured to the outer terminal of the boom 6, the guy rope passing through the groove 10, to the rear of the machine where it is wound on a drum. 12, which is secured to a shaft 13, having thereon a gear wheel 14, which meshes with a pinion 15, a crank 16 bein supplied to operate the drum by means of t e pinion 15 and the gear wheel 14. A ratchet wheel 17, is secured on the shaft of the drum and operates with the pawl 18, to hold the drum securely when desired. Near the top of the forward braces 4 are secured adjustable braces 19, which are fastened as indicated in Fig. 5, so that they may swing forward when the frame is lowered and be made to rest on the brackets 20, on the standards 21. I also provide anchors 22, which are pivotally secured on the middle transverse member 3. At the outer terminal of the boom is secured a block 23, to

for the hoisting of the load.

I the guy rope 11,

The block 27, as shown in Fig. 4 maybe slipped along on the forward transverse member 3, and be held in any osition in this manner by a pin 28. Attac ed to the boom 6 is a chain 29, which may be secured to the hook on one of the braces 4. By hook.- ing any1 one of the different links of the chain 29 to t e hook on one of the said braces 4, the operative length of the chain is adjusted to permit the boom 6-to have the desired limitation to its swing. The chains 25, which are secured to the block 24 have rings at their free terminals and hooks 30, the eyes of which inclose the chain but are not large enou h to permit the rings at the terminals of the chain to pass therethrough. Near the upper portion of each of the chains 25 is a hook 31, secured to a ring which forms part of the chain. I also provide a chain 32, having rings 33, at its terminals. By my construction of the frame, I am able to evenly distribute the strain throughout the body of the machine, as the boom pivots in the transverse member 3 which is slightly nearer the rear of the frame than to its forward end. In addition assists to counterbalance the load 34. This keeps the center of gravit of the machine with the load applied, wel under the base of the frame and low down. The adjustable braces 19, which are designed to be inserted into the ground, afford further means to keep the machine upright under of the auxiliary chain 32 heavy strains and when working in difficult ositions. These adjustable braces 19 may ave enlarged lower ends if need be, to rest on the ground and prevent the braces from sinking therein. The chains which are provided to be secured to the load, are constructed in the manner set forth above in order that they may be secured to loads of various dimensions. In handling ordinary logs or similar loads, the hooks 30 may be inserted one at either end of the log and a firm hold may be obtained in this Way and the hoist rope brought in motion to lift the log to any desired height. However, if a shorter log is to be secured by the hooks on the chains, it is necessary to use shorter chains and I therefore provide the hooks 31 to which may be secured the rings on the outer terminals of the chains 25, the rings on the hooks 30, slipping upward to adjust themselves to the new position necessa by the doubling, of the lower portions of t e chains 25. In this way short logs may be readily and firmly secured. When a number of logs are to be lifted and the chains 25, are not long enough to encircle them, the auxiliary chain 32 is made use of, which may be applied in many different ways such as by fastening one ring 33 to the hook 31, and bringing the other end with its ring 33, around under the logs, securing the ring to the hook 30, on the other chain 25. When the chains are secured in this way the logs may be released by slight movements of the will release. the book 30- chains' 25, which from the ring 33.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: V 1.
